Descriptions

The Modern Events Calendar plugin for WordPress is vulnerable to arbitrary file uploads due to missing file type validation in the set_featured_image function in all versions up to, and including, 7.11.0. This makes it possible for authenticated attackers, with subscriber access and above, to upload arbitrary files on the affected site's server which may make remote code execution possible. The plugin allows administrators (via its settings) to extend the ability to submit events to unauthenticated users, which would allow unauthenticated attackers to exploit this vulnerability.

El complemento Modern Events Calendar para WordPress es vulnerable a la carga de archivos arbitrarios debido a la falta de validación del tipo de archivo en la función set_featured_image en todas las versiones hasta la 7.11.0 incluida. Esto hace posible que atacantes autenticados, con acceso de suscriptor y superior, carguen archivos arbitrarios en el servidor del sitio afectado, lo que puede hacer posible la ejecución remota de código. El complemento permite a los administradores (a través de su configuración) ampliar la capacidad de enviar eventos a usuarios no autenticados, lo que permitiría a atacantes no autenticados explotar esta vulnerabilidad.
